CLOSURE FOR COLIiAPSIBLE TUBES.

Specification of Letters Patent.

Application filed April '15, 1916. Serial No. 91,283.

To (ZZZ whmn it may concern Be it known that 1, Cuaniins F. KnuiuoAN, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York. have invented certain new and useful improvements in Closures for Col-- lapsible Tubes, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain impr0vc ments in containers or tubesof pliable metal, such as are used for holding tooth paste, shaving cream and the like, and commonly known its-collapsible tubes.

It. is one of the objects of the invention to provide a distributing device for such containers, including a distributing nozzle and tap which will b permanently secured thereto, so that it cannot be readily re moved therefrom and lost.

- It is a further object of the invention to provide such a distributing device 'which shall be of such construction to permit the container to be ctiectually closed when not in use, and thus prevent the entrance of foreign matter to the container. it is a further object of the invention to provide a constrimtion which will reduce to a minimum the grinding of the parts on opening and closing of the container, thus preventing bits of metal from getting into the coutainer, which may cause discoloration of the contents thereof.

With these and other objects in view, the invention consists in certain novel parts and constructions"which can best be understood from a detailed description of the same, and such description will now be given in connection with the accompanying drawings, in which 7 Figure 1 is a side view of a flexible metal tube with the improved distributing device shown in section in closed position;

Fig. 2 is a similar view showing the parts in open or distributing position, part of the tube being broken away; and

Fi 3 is a section taken on line 33 of g Y Fig. 2.

Referrin now to these drawings, the container mauled l'is of the well-lmown type now employed for holding tooth paste, shaving creamand the like, madeof pliable 7 metal, commonly .known in -th'e art as a;

I may vary somewhat in aconstru collapsible tube, the contents being-removed from the container by compressing it.

In accordance with the invention, the container or tube is provided with a distributing nozzle having a distributing opening and with a closing cap cooperating with,.,the nozzle to clos the opening so as to effectually prevent the entrance of foreign matter to the tube. The distributing opening is, furthermore, preferably formed so that the contents of thecontainer will not be smeared on the cap and prevent a complete closing of the opening. While the nozzle might be formed separately from the 0011- tainer and be suitably secured thereto, in the preferred construction, and as illustratd, the tube is formed with an integral nozzle in which is located the distributing opening. In the preferred construction, as that shown in Figs. 1 and 2, the top of the container is stamped or otherwise shaped to form a projection 3 which projects inwardly a short distance into the container and is for I- a purpose hereinafter referred to, formed with an interi-orly (threaded aperture or opening 4, closed at the bottom, as shown .8 0 Around this projection 3 near its top is formed, by suitably striking up the metal, a recess 5, the outer walls of which are of less diameter than the body of the tube and form i a flange 6, the upper end of which is flat, as

indicated at 7, to provide a seat for the cap; The distributing opening leads from this rccess 5 and may be of various configurations. Preferably, there will be but one opening, as indicated at 8, and preferably, this opening is formed in a plane diag'ona to the vertical plane of the tube. Thepur: pose of this construction is that, when thepaste is ejected from the tube, it will be H forced out at an angle to the nozzle and cap, 95 and gumming of the cap will be prevented.

F urthermorn, in the best constructions, and.

as shown, this opening will xtend from the upper portion of the recess 5-at the'junction between the top edgeof the flange fiend tar-16d 7, so that the entrance to thecdntainer 1? bits of metal, which might be ground during the opening and closing mo'velneu of the cap, is to a large extent 26V" Cooperating with the-mozz ejo the tainerl is a closing top or cap. This" cap ction b il1ustrated,.is pr fcrab yi n ill f fl furthermore accidentally removed from the in Figs. 1 and 2. As there shown, the cop is formed with n flat top and is provided with a milled edge 9 to p ovide it convenient 'ipping surface for operating it. The cap as an interiorly depending stem 10, having its lower portion threndech is st 11. This cap Works in the threaded opening at in the nozzle, befo a, referred to, this o iening being of suflicient depth to receive the stem. This cap-piece is formed nsshown, around the stem 10 with n depending flange or shirt 12, which is dimensioned that when the ca is in closed position, this tinge extends be 0W the distributing openL 8 and co operates with the flange (3 no "ire re red to, and effectually closes the opening. in the best construction, a s dish oil suitable material, as a thin dish of C(H'l; i l, is provided in the interioroi' the cap for n'iore efiectually'closing the opening To affect one of the main objects of the invention, a construction is provided where by the cap when once forced. into position cannot be readily removed. from the tube and loss or inisplacement of the cop is prevented. This construction may, of course, be considerably varied. In the construction illustrated in Figs. 1 and 53 which :1 convenient one,- the inner edge of the sent 7 which is marked '7 is left with a slight flange of metal which, after the threaded eiid of the cap hes been screwed into the opening 4, is turned in over and forms e stop against which the threads 11 on the end 10 of the cup will be stop 'ied and thus effectually preventing the cap from being :llQQ.

NVh'ile the invention has be 1 shown and described in'w'net is thought to be its best and most convenient form, it will be under stood that variations may be made in the specific form and nrrnnomnmit of the nozzle Leeenoi and cap, and that such variations are within the scope of the invention and claims hereunto appended.

That is claimed is: v i

1. A container for tooth paste and the like, ccn'iposed of pliable metal and provided with n distributing nozzle having a flat top forming it sent, a distributing opening below the sent and extending singularly to the vertical. plane of the nozzle so as to distribute materinl sidcwise therefrom, a closing cap having threaded eng'z gement with the nozzle and :1 part movable to a position below the distributing opening to entirely close the sense and seating on the list top of the nozzle when in closed posii'ion, and means for preventing the cap from being entirely unsclffiired from the nozzle.

A tube for tooth paste and the like, composed of pliable metal and provided with it distributing nozzle formed integral therewith. having a flat top forming a seat, said nozzle being formed with an inwardly projecting interiorly threaded portion, a distributing opening at the side of the nozzle extending :ingulnrly thereto so as to distribute material sideivisc from the nozzle and :1 closing cap having a stem in threaded engagement with said threaded port-ion and it shirt closing the distribilting opening in the nozzle, said cap bein prevented from being entirely unscrewed from the nozzle by bonding in. the notzil of the nozzle seat to form :1, stop above the threads of the cop stein.

In testimony whereof, I have hereunto set no; hand, in the presence of two subscribing witnesses.
